ELECTRICAL SYSTEMS

Purpose

Typically used to turn on the electric blade clutch and to
function as part of the safety interlock system.

How It Works

Contacts inside this DPDT switch electrically connect
various terminals. It is actually just two SPDT switches
tripped by a single lever. One of the SPDT switches is
connected to the electric PTO clutch. When in the off
position, this side of the switch is open. The other half
of the switch is used by the safety interlock system.
When the clutch is off, this side of the switch is closed.
This allows current to keep the kill relay energized so
that the mag is not grounded out.

Testing

1.
Disconnect the switch from the wiring harness.
2.
Verify the conditions on the diagram.
